Specification of Letters Patent.

Patented Apr. so, 1918.

Application filed August 14, 1917. SerialNo. 186,226.

To all whom it may 001L067'7'L Be it known that I, ROBERT A. GALLY, acitizen of the United States, and residing at Cincinnati, in the countyof Hamilton and State of Ohio, have invented certain new and usefulImprovements in Music- Player-Pneumatic Counterweights, of which thefollowing is a specification.

In applicants prior Patent #891,801, June 23, 1898, is shown and claimedan extended heel lever striker pneumatic, preferably adapted to causethe heel lever to always he held in contact with the abstract which itwas to operate. In some instances,

' where the material or any horizontal downward stroke pneumatic 1 israther stiif, or where there is an extra heavy abstract or sticker 2 orother parts co-acting with the heel lever 3 or other lever of thepneumatic l, as shown herein and in applicants other application#184,355, filed Aug. 3, 1917, and #184,677, filed Aug. 6, 1917, and#185,161, filed Aug. 8, 1917, it is desirable to use a counterweight 4:to partly or wholly overcome or exceed any stiffness of the coveringmaterial of the striker pneumatic 1 or the weight of any sticker 2 orother part as nut 5 bearing down on the heel lever extension 3, suchcounterweight 4 being of such size,

and at such position on the pneumatic 1 forward of its hinge 6, as togive the most desirable balance of weight for satisfactory actuation ofsuch striker pneumatic 1.

It is to he understood that this coimterweight feature may be used withany horizontal down stroke pneumatic, either in upright or grand pianos,and whether for overcoming the stiffness of the covering material ofsuch pneumatic, or against the 4 weight of any levers, heel levers,stickers, or

other parts that tend to open the pneumatic by raising its moving board.

The drawing herewith is of a side view of a piano keyboard and keybedwith the present invention shown as placed under the keys and keybed,but it is to be understood that such counterweighted pneumatics may beused either above or below the keys, and for either grand or otherpianos, or in any part of a pneumatic musical apparatus where they maybe desirable, and be subject to What I claim as my invention, whichis 1. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; a member actuated by and connected to the saidmoving board and whose weight constantly acts to raise the said movingboard; and a weight attached to the said moving board at a distance fromthe hinged end thereof.

2. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; an arm fixed with the said board and extendedbeyond its hinged end; and a weight attached to the said moving board ata distance from the hinged end thereof.

3. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; an arm fixed with the said board and extendedbeyond its hinged end; an actuating means resting on the extended partof the said lever, and a weight attachedto the said moving board at adistance from the hinged end thereof.

4. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; an arm fixed with the said board and extendedbeyond its hinged end; a vertical sticker rest ing on the extended partof the said lever; and a weight attached to the said moving board at adistance from the hinged end thereof.

5. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; aweight attached to the said moving board at adis tance from the hinged end thereof; and an intermittent air serviceconnected to said pneumatic to cause the downward movement of the saidboard.

6. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; a weight attached to the said moving board at adistance from the hinged endthereof; and an intermittent air serviceconnected to said pneumatic to cause the downward movement of the saidboard which is assisted by the said weight.

7, A horizontal striker pneumatic having attached to the said movingboard at a dis-' tance from the hinged end thereofyandan intermittentsuction air service connected to said pneumatic to cause the downwardmovement of the said board;

8. A horizontal striker pneumatic having a moving board at its upperside, the said board being downwardly movable at one end thereof andhinged at its other end; a weight attached to the said moving board at adistance froln'the hinged end"thereof; an'dan intermittent suction airservice connected to said pneumatic to cause the downward movement'ofthe said board which is assisted by the said weight. g
